View Full Version : VF or AA (E36) supercharger kit?

03-19-2010, 05:37 PM
I have a 1993 525i. It has the same motor as the E36 (M50TUB25)which VF-engineering and Active Autowerke both makes supercharger kits for. I spoke with both companies and they said both would fit more or less.

AA said I would have to modify the mounting of the intercooler, and VF said I would have to use their E38 intake instead of the E36.

Should I get the intercooled AA C-30 Rotrex kit?
Or the Non-intercooled VF Vortex kit?
What company has a better reputation for quality, tuning and performance?

I live in Southern California so the summers can get hot. But the PSI on both kits is under 8psi so I don't know if it matters as much. The AA kit will be about $500 more and the hassle of dealing with the intercooler. Over all which is better for my application?

Thanks guys!

AA all the way intercool it! to keep the temps down.

I have a friend that dynoed his E46 325 and nice numbers came out 250 RWHP so he doubled the cars HP.

good luck!
